Physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Published Early arrival and expansion of palaeolithic people on Cyprus
(via sciencedaily.com)
Original source 
The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.
Published To optimize guide-dog robots, first listen to the visually impaired
(via sciencedaily.com)
Original source 
What features does a robotic guide dog need? Ask the blind, say researchers. A new study identifies how to develop robot guide dogs with insights from guide dog users and trainers.
Published Jet-propelled sea creatures could improve ocean robotics
(via sciencedaily.com)
Original source 
Scientists have discovered that colonies of gelatinous sea animals swim through the ocean in giant corkscrew shapes using coordinated jet propulsion, an unusual kind of locomotion that could inspire new designs for efficient underwater vehicles.
Published Robotic 'SuperLimbs' could help moonwalkers recover from falls
(via sciencedaily.com)
Original source 
SuperLimbs, a system of wearable robotic limbs, can physically support an astronaut and lift them back on their feet after a fall, helping them conserve energy for other essential tasks.
Published Animal brain inspired AI game changer for autonomous robots
(via sciencedaily.com)
Original source 
A team of researchers has developed a drone that flies autonomously using neuromorphic image processing and control based on the workings of animal brains. Animal brains use less data and energy compared to current deep neural networks running on GPUs (graphic chips). Neuromorphic processors are therefore very suitable for small drones because they don't need heavy and large hardware and batteries. The results are extraordinary: during flight the drone's deep neural network processes data up to 64 times faster and consumes three times less energy than when running on a GPU. Further developments of this technology may enable the leap for drones to become as small, agile, and smart as flying insects or birds.
Published Summers warm up faster than winters, fossil shells from Antwerp show
(via sciencedaily.com)
Original source 
In a warmer climate, summers warm much faster than winters, according to research into fossil shells. With this knowledge we can better map the consequences of current global warming in the North Sea area.
Published Robots' and prosthetic hands' sense of touch could be as fast as humans
(via sciencedaily.com)
Original source 
Research could pave the way for a prosthetic hand and robot to be able to feel touch like a human hand. The technology could also be used to help restore lost functionality to patients after a stroke.
Published Researchers use artificial intelligence to boost image quality of metalens camera
(via sciencedaily.com)
Original source 
Researchers have leveraged deep learning techniques to enhance the image quality of a metalens camera. The new approach uses artificial intelligence to turn low-quality images into high-quality ones, which could make these cameras viable for a multitude of imaging tasks including intricate microscopy applications and mobile devices.
Published Cats purrfectly demonstrate what it takes to trust robots
(via sciencedaily.com)
Original source 
Would you trust a robot to look after your cat? New research suggests it takes more than a carefully designed robot to care for your cat, the environment in which they operate is also vital, as well as human interaction.
Published Today's world: Fastest rate of carbon dioxide rise over the last 50,000 years
(via sciencedaily.com)
Original source 
Today's rate of atmospheric carbon dioxide increase is 10 times faster than at any other point in the past 50,000 years, researchers have found through a detailed chemical analysis of ancient Antarctic ice.
Published A better way to control shape-shifting soft robots
(via sciencedaily.com)
Original source 
A new machine-learning technique can train and control a reconfigurable soft robot that can dynamically change its shape to complete a task. The researchers also built a simulator that can evaluate control algorithms for shape-shifting soft robots.
Published Robotic system feeds people with severe mobility limitations
(via sciencedaily.com)
Original source 
Researchers have developed a robotic feeding system that uses computer vision, machine learning and multimodal sensing to safely feed people with severe mobility limitations, including those with spinal cord injuries, cerebral palsy and multiple sclerosis.
Published Generative AI that imitates human motion
(via sciencedaily.com)
Original source 
Walking and running is notoriously difficult to recreate in robots. Now, a group of researchers has overcome some of these challenges by creating an innovative method that employs central pattern generators -- neural circuits located in the spinal cord that generate rhythmic patterns of muscle activity -- with deep reinforcement learning. The method not only imitates walking and running motions but also generates movements for frequencies where motion data is absent, enables smooth transition movements from walking to running, and allows for adapting to environments with unstable surfaces.
Published Human activity is making it harder for scientists to interpret oceans' past
(via sciencedaily.com)
Original source 
New research shows human activity is significantly altering the ways in which marine organisms are preserved, with lasting effects that can both improve and impair the fossil record.
Published Swarms of miniature robots clean up microplastics and microbes, simultaneously
(via sciencedaily.com)
Original source 
When old food packaging, discarded children's toys and other mismanaged plastic waste break down into microplastics, they become even harder to clean up from oceans and waterways. These tiny bits of plastic also attract bacteria, including those that cause disease. Researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.
Published It flickers, then it tips -- study identifies early warning signals for the end of the African humid period
(via sciencedaily.com)
Original source 
Tipping points in the climate system can be the result of a slow but linear development. However, they can also be accompanied by a 'flickering', with two stable climatic states that alternate before a final transition occurs -- and the climate tips permanently.
Published Caterbot? Robatapillar? It crawls with ease through loops and bends
(via sciencedaily.com)
Original source 
Engineers created a catapillar-shaped robot that splits into segments and reassembles, hauls cargo, and crawls through twisting courses.
Published Stretchable e-skin could give robots human-level touch sensitivity
(via sciencedaily.com)
Original source 
A stretchy electronic skin could equip robots and other devices with the same softness and touch sensitivity as human skin, opening up new possibilities to perform tasks that require a great deal of precision and control of force.
Published Random robots are more reliable
(via sciencedaily.com)
Original source 
New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.
